I have a winforms application where I create a Dataset of data items and drag it onto my form which then generates a set of Bound fields on the form. All of the fields are auto generated textboxes. Two of the fields are Category and Sub Category, which are related, of which I have created a second Dataset containing the two tables and the link definition. Now the difficult part is the implementation of these dataset's. If I drag the first dataset onto my form I get all of the fields generated for me as text box's, including Category and Sub Category. But I need these latter two fields to be related and interact with each other. I also need these two fields to be of a C1Combo type but still update to the data source through their bound TextBox's. I can't figure out how all this can be achieved, I did something similar a few years ago and I remember that I found the solution through one of Beth Massi's video series. These videos seem to have reluctantly disappeared off the MSDN site. Can you help to point me in the right direction to solve these problems? I am developing in C# using Visual Studio 2012.
Thanks
